Case Discussion

Meningiomas are the most common extra-axial tumours of the central nervous system and account for 14-20% of all intracranial neoplasms. They are a non-glial neoplasm that originates from the arachnoid cap cells of the meninges. Petroclival meningioma arises in the upper two thirds of the clivus at the petroclival junction medial to the fifth cranial nerve.
